中文摘要	This paper introduces our recently conducted high-resolution imaging experiment of a moving train by ground-based Ku-band radar with 4GHz bandwidth. The radar system design is briefly outlined, especially for the RF subsystem. The stepped-frequency chirp signal (SFCS) is used for realizing the 4GHz signal bandwidth. Synthetic aperture radar processing mode is used although the radar is stationary while the target is moving. The obtained radar images are presented and the electromagnetic scattering characteristics are analyzed. The radar images of 2GHz bandwidth are also presented for comparison with that of 4GHz bandwidth. In the obtained radar images, the scattering structures of windows, doors, ventilators of air-conditioner, and the compartment bodies are well shown.
